If these different sub-groups behave differently in terms of post surgical progression of disease (PSPD) rates or other clinical variables, then better treatment and prognosis could be predicted. Methods: This was a retrospective cohort study. Patients who have undergone surgery for removal of a non-functioning pituitary adenoma at Emory University Hospital served as the source for all data used in this study (n = 184). Data were collected from a database of electronic medical records (EMRs) for these patients in 2010 documenting clinical and demographic variables including treatment and PSPD. Results: Risk for PSPD did not differ by adenoma subtypes: follicle-stimulating hormone (FSH+), luteinizing hormone (LH+), or those that do not stain positive for any hormone (non-functioning, or NF?) (p = 0.971). There were two clinical characteristics statistically related to adenoma subtype: altered mental status and the anterior-posterior (AP) dimension of pre-operative adenomas. PSPD was related to several clinical characteristics, including gender, previous adenoma, post-operative residual, and follow-up time.展开更多
